I just merged https://github.com/mautic/mautic/pull/8337 into the staging branch, which means this PR will make it into Mautic 2.16 (expected beta release on Jan 30). This is a short term fix which maintains current Maxmind behavior. For long term consideration, please read my comment on the PR: https://github.com/mautic/mautic/pull/8337#issuecomment-578953976
